INK-FOUNTAIN FOR PRINTING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 367,526, dated August 2. 1887.

Application filed July 1, 1886. Serial No. 206,783. (No model.)

' feet and efficient manner.

In the accompanying drawings, Figu rel represents a side elevation of alithographic press with myimproved inkfountain. Figs. 2 and 3 are respectively a vertical central section and an end View of the ink-fountain, a part of the ink-roller being broken away. Fig. 4 is a plan of the sectional knife for regulating the inksupply; Fig. 5, a plan of parts in Fig. 3, the roller not being shown. Figs. 6 and 7 are a vertical transverse section and a top view of an ink-fountain with my regulatingknives, showing a modified form of adjusting mechanism. Fig. 8 is a detail of one of the regulating-knives of the ink-fountain.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents an ink-fountain for lithographic and printing presses, which ink-fountain is constructed of an ink-roller, a, side walls, I) b,which are provided with bearings I) b for the ink-roller (t, an inclined bottom, (Z, and a number of independent] y adjustable regulatingknives, e c, which,in connection with the bottom (1," serve to hold the knives in position to adjust them toward or away from the ink-roller a. A top plate, f, extends over the knives and retains them in position by means of short bindingscrews f which pass through the bottom (Z and holes or slots of some of the knives and of the top plate, f, as shown, respectively, in Figs. 4, 6, and 7. The regulating-knives e e are adjusted toward or away from the inkroller a by adjustingserews g, which pass either through the bottom (Z and serve to raise or lower the front ends of the knives, as shown in Fig. 2 or 3, or by screws 9, which engage the forked rear ends of the knives and sockets at the rear part of the top plate, f, as shown in Figs. 6 and 7, so as to adjust the regulatingknives e e in forward or backward di' rection toward or away from theink-roller between the bottom and top plate of the inkfountain. In either case the individual knives may be adjusted independently of each other toward or away from the ink-roller, so that a greater or smaller quantity of ink may be supplied at some points to the fountain than at other points, or the supply of ink entirely in terrupted at some points, according to the work to be done on the lithographic or printing press. The inkfountain is brought by the adjustable knives within full control, so that not only a more perfect supply of ink, and consequently better printing, is produced, but also a considerable saving in ink produced, as the same is more effectively distributed and conveyed to thcplaces where the same is wanted. Having thus described my invention,I claim as new and desire to secure by Letters Patent-- As an improvci'nent in ink-fountains for 11th ographic and printing presses, the combination of an ink-roller, the adjustable regulating doctor blades or knives, the widened bottom plate on which the knives are supported, the retaining top plate, and screws for adjusting and holding the knives in position, substantially as described.

In testimony thatI claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
